People make this mod sound so difficult. Seriously, get under the left pipe, use those guns of yours and pull the damn hose off .

Just pull the plug. Why screw with the hose? If you have a JB4 just turn off the flap unit.

To answer youre question, the car needs time to adapt to the difference in backpressure. You will only loose low end torque for a while until the car adapts, same as with any exhaust.

Btw this thread is almost a year old lol so no more reviving

Will it simply stop sucking air or is it gonna keep trying and possibly damage something??
The car explodes.

Thats actually not wrong. It takes time for the dme to account for a change in backpressure. Low end torque is affected until it adapts.
